1) Using balanced valve disk structure, the axial unbalanced force is small, allows the differentialpressure is big, good stability
2) Sleeve strong interchangeability, tear open outfit is convenient, easy to maintenance
3) All metal valve core structure for a variety of workplace, reach the standard level IV leakage, ZXMQ type sealing structure of valve core reach the standard grade VI leakage
4)Body according to the fluid mechanics principle designed to uniform the low flow resistance port, wide adjustable range, inherent adjustable ratio of 50, rated flow coefficient increases by 30%
5) Actuator adopts more spring structure, highly reduced by 30%. 30% reduction in weight

We are valve manufacturer specialized in the industrial valves utilized in the server application environment against high temperature, high pressure, high corrosive and low temperature or cryogenic application ranging from petrochemical, offshore, chemical, gas, power plant, shipyard to long distance pipeline and pharmacy or other industries. Valve types vary from ball valve, globe valve, check valve, gate valve, butterfly valve to plug valve, and also from tank bottom valve, sampling valve, double block & bleed valve, strainer to sight glass.
Valve material are available from Titanium, Nickel alloy, Zirconium, Nickel-Aluminum-Bronze, (Super) Duplex to alloy 20#, 904L, 310S, 321, 347 or other anti-corrosive alloys. With emphasis on quality consistency and innovative design, we gradually turn to be reliable business partner for plenty engineering companies and end users all over the world.
